LAS VEGAS, Oct 22 (Reuters) - At the world’s biggest market program in Las Vegas high-end jets are luring buyers with their sleek shapes, luxurious cabins - and significantly, their usage of alternative fuels.

Fuel manufacturers and jetmakers are keen to display unique forms of air travel fuel deemed less hazardous to the climate, from utilized cooking oil to the definitely less attractive meat waste.

Business jet operators, like airline companies, have acquiesced ecological pressure on air travel and dedicated to cutting in half carbon emissions by 2050 compared to 2005.

Their hope is that adopting eco-friendly fuel to suppress emissions might make service jets more attractive to environmentally conscious purchasers - particularly corporations dealing with concerns over sustainability from investors or green project groups.

The schedule of less contaminating private jets might likewise spare the abundant and popular the unfavorable promotion experienced by Britain’s Prince Harry and his partner Meghan over a recent private jet journey to southern France.

Five Gulfstream jets on display in Las Vegas are using California-produced fuel from inedible beef tallow.

The current waste-based fuels include “fats, grease and oils that are byproducts of the food market,” stated Bryan Sherbacow, chief business officer of Boston-based biofuel manufacturer World Energy, which produces fuel from meat waste used by Gulfstream.

“All of our product is inedible.”

A few of the other 79 airplane on screen are expected to be powered by 150,000 gallons of other eco-friendly fuel mixes expected to be pumped at the show.

FLIGHT SHAMING

Private jets represent less than 0.1% of total yearly carbon emissions globally, however can discharge, typically, as much as 20 times more carbon emissions per traveler mile than jetliners, according to the London-based private charter company Victor.

Prince Harry has actually defended his occasional usage of personal jets to ensure his family’s security, and has actually stated that on the rare occasions he does not fly commercially he offsets his emissions.

But planemakers say incidents such as the furore over his travel plan have added fresh obstacles for a market currently making every effort to justify its contribution to cutting corporate expenses.

“Incidents of flight shaming involving making use of private jets are regrettable when you think about that our market has actually delivered fuel effectiveness improvements of 40% over the previous 40 years,” said Bombardier Aviation Coleal.

Bombardier believes increased sustainable fuel usage will help the market make inroads with corporations and wealthy buyers. According to market data, billionaires only have a 19% organization jet ownership rate.

But even an image makeover - with jets sporting sticker labels like “this airplane flies on sustainable fuels” and organisers including alternative fuel pumps for going to airplanes - is unlikely to satisfy all critics at the Oct 22-24 high-end jet occasion.

Environmentalists and some analysts remain doubtful that biojetfuels, generally combined 50-50 with kerosene, will make a significant impact on public understandings about luxury travel.

“No quantity of jatropha curcas or Brazil-nut fuel can make company jets look eco-friendly,” said aviation analyst Richard Aboulafia.

Demand from company jet operators for renewable fuels now far exceeds supply and their interest could drive future production, Sherbacow said.

World Energy, which produces 40 million gallons of biofuel at its California plant, might broaden production approximately 150 million gallons by 2022.

Corporate charter business and consultants are also seeing more interest from customers who want to purchase carbon credits to offset emissions from their flights.

Brian Proctor, CEO of Mente Group, a U.S. consultancy, stated emissions played a role in a corporate jet utilization study his business just recently completed for a Fortune 500 business.

“At the end of the day, I think that price, cost per hour, range, speed and efficiency, that’s still the (sales) motorist. But I believe people are becoming more familiar with the sustainability of operations and how it impacts the planet.” (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
